Abstract

Disclosed are (1) a novel galactosyl-cyclodextrin having a galactosyl group bonded to a hydroxyl group of a glucosyl group of a cyclodextrin via an .alpha. -bond and a method of producing the galactosyl-cyclodextrin; (2) a novel galactosyl-cyclodextrin having a galactosyl group bonded to a hydroxyl group of a glucosyl group of a cyclodextrin via a .beta. -bond and a method of producing the galactosyl-cyclodextrin ; and (3) a novel mannosyl-cyclodextrin having a mannosyl group bonded to a hydroxyl group of a glucosyl group of a cyclodextrin via an .alpha. -bond and a method of producing the mannosyl-cyclodextrin. The new branched cyclodextrins are expected to be widely useful in various fields of drug industry, food industry and cosmetic industry.
